Summary of the Invention

Problems to be Solved by the Invention

[0004] The taping tape described in Patent Document 1 is a strip-shaped tape for promoting the assistance and improvement of body functions by winding it around the body to protect and fix joints, muscles, etc.

[0005] Unlike such a strip-shaped taping tape, the present invention relates to a taping material for reducing pain in a part by selectively attaching it to the skin at a painful or hardening site. That is, an object of the present invention is to provide a taping material that can reduce abnormal movement and pain at the attachment site by attaching it to a part of the human body.

Means for Solving the Problems

[0006] According to the present invention, there is provided a taping material including a base material having a hexagonal or honeycomb-shaped planar shape, and an adhesive layer having a hexagonal or honeycomb-shaped planar shape superimposed on the base material. The base material is composed of a knitted fabric in which non-stretch fiber yarns and elastic fiber yarns are knitted so as to have stretchability both in the longitudinal direction and in the transverse direction.

[0007] Since the base material has a hexagonal or honeycomb-shaped planar shape similar to the skin structure and is a knitted fabric having stretchability both in the longitudinal direction and in the transverse direction, its impact dispersion ability is very excellent. Therefore, by attaching it to a part of the body that hurts when moved or hurts when pressed, the skin can regain its flexibility and reduce the pain of muscles and joints. The human skin is an aggregate of polyhedrons composed of 8 hexagonal faces and 6 quadrilateral faces called Kelvin tetrakaidecahedrons, and has a scaly structure in which hexagons are continuous when viewed from the surface. Therefore, the skin moves along the hexagonal structure, and it is considered that the impact received on one side of the hexagon is dispersed to each side and washed away. Therefore, by selectively attaching a taping material that closely resembles normal flexible skin as in the present invention to the skin at a painful or hardened area, the flexibility of the skin in that part is restored, the pain is dispersed toward any of the six sides, and the pain of muscles and joints can be reduced. By attaching another taping material adjacent to the side where the pain of one taping material is dispersed, the pain is dispersed and reduced in the other taping material. By repeating this adjacent attachment of the taping materials, the symptoms can be finally significantly improved.

[0008] It is preferable that the base material is formed by cutting a Raschel knitted fabric composed of non-stretch fiber yarns and elastic fiber yarns along the wale, the non-stretch fiber yarns form a net with chain stitch as the pillar, and the elastic fiber yarns are inserted along the chain stitch.

[0009] It is also preferable that both the base material and the adhesive layer are configured to have a single regular hexagonal plane.

[0010] It is also preferable that both the base material and the adhesive layer are configured in a honeycomb shape having at least one hexagonal hole. The honeycomb shape is a porous shape like a beehive, but in the present invention, it may be a shape consisting of a single hole of a beehive or a porous shape.

[0011] It is also preferable that the first reed organization and the second reed organization every other row of the inextensible fiber yarn form a net with chain knitting as columns meandering over several rows in a left-right symmetric manner, and elastic fiber yarns are inserted into each row.

[0012] In this case, it is also preferable that the tightening force at 30% elongation in the row direction is 60 to 85 g per 25.4 mm width, and the tightening force at 30% elongation in the course direction is 30 to 50 g per 25.4 mm width.

Effects of the Invention

[0013] According to the present invention, by attaching to a part of the human body that hurts when moved or hurts when pressed, the skin regains flexibility and the pain of muscles and joints can be reduced. By attaching another taping material adjacent to the side where the pain of one taping material is dispersed, the pain is dispersed and reduced in the other taping material. By repeating this adjacent attachment of the taping materials, finally, the symptoms can be significantly improved.

Modes for Carrying Out the Invention

[0015] Figure 1 schematically shows the configuration of an embodiment of the taping material of the present invention.

[0016] As shown in Figure 1, in the taping material 10 of this embodiment, an adhesive layer 12 having a regular hexagonal planar shape is superimposed on the lower surface of a knitted fabric 11 (corresponding to the base material of the present invention) having a regular hexagonal planar shape, and a release paper 13 having a regular hexagonal planar shape is adhered to the lower surface of this adhesive layer 12.

[0017] Figure 2 schematically shows an enlarged part of the knitted fabric 11 in the taping material 10 of this embodiment, and Figure 3 shows a part of the cross-section taken along line A-A of Figure 2. Hereinafter, the configuration of the knitted fabric 11 will be described using these figures.

[0018] The knitted fabric 11 is a Raschel knitted fabric using non-elastic fiber yarns and elastic fiber yarns. As the non-elastic fiber yarns, polyester multifilament yarns (75 denier) are used, and as the elastic fiber yarns, spandex yarns (140 denier) are used. This Raschel knitted fabric is cut along the wale to form a net with non-elastic fiber yarns as the chain stitch as the pillar, and elastic fiber yarns are inserted along the chain stitch to form the knitted fabric 11.

[0019] That is, non-elastic fiber yarns 11a are passed through the first bar of the Raschel knitting machine one by one to form a 20 / 24 / 42 / 46 / 42 / 24 weave, and non-elastic fiber yarns 11b are passed through the second bar one by one in the same way to form a weave symmetric to the left and right of the first bar. Further, elastic fiber yarns 11c are passed through the third bar one by one and inserted in a 22 / 00 / 22 / 00 / 22 / 00 weave, and elastic fiber yarns 11d are passed through the fourth bar one by one and inserted symmetrically to the left and right of the third bar. The tension of the elastic fiber yarns 11c and 11d during knitting was set to 20 g.

[0020] The knitted fabric 11 thus obtained is a power net in which elastic fiber yarns 11c or 11d are inserted into each chain stitch of a 6-course net. Each chain stitch is connected to the left chain stitch every 6 courses by sinker loops of inelastic fiber yarns 11a or 11b forming this chain stitch, and is connected to the right chain stitch at a position shifted 3 courses forward and backward from the connecting portion 11e. That is, the connecting portions 11e formed by sinker loops are arranged in a zigzag pattern, and a long hole 11f spanning 5 courses is formed between the front and rear (upper and lower in FIG. 2) connecting portions 11e, 11e.

[0021] An acrylic adhesive obtained by crosslinking a polymer of 2-ethylhexyl acrylate, butyl acrylate, acrylic acid, and 2-hydroxyethyl methacrylate with an isocyanate compound (trade name "Coronate L", manufactured by Nippon Polyurethane Industry Co., Ltd.) is applied to the back surface of this knitted fabric 11 to a thickness of 50 μm (dry) to form an adhesive layer 12. A release paper 13 is attached to the back surface of this adhesive layer 12, and then slit into a width of 50 mm to obtain a taping material 10 (the taping material of Example 1 described later). As shown in FIG. 3, a hole 12a is formed in the adhesive layer 12 at a position corresponding to the long hole 11f of this taping material 10.

[0022] As described above, the taping material 10 of the present embodiment is formed by cutting an elastic adhesive cloth obtained by attaching an adhesive layer 12 and a release paper 13 to one side of a raschel fabric composed of non-elastic fiber yarns and elastic fiber yarns along the wales. A net is formed in which the first and second wale tissues consisting of non-elastic fiber yarns that skip every other wale meander in a left-right symmetric manner over several wales with chain stitch as the column, and elastic fiber yarns are inserted for each wale to obtain elasticity in the longitudinal and transverse directions. This elastic fiber yarn is a synthetic fiber yarn having stretch elasticity such as spandex. The stretch characteristics of the raschel fabric into which this elastic fiber yarn is inserted change depending on the thickness, arrangement density, and tension set during knitting of the elastic fiber yarn. The thickness of the spandex yarn used is not limited to 140 denier, and it is preferably in the range of 140 to 420 denier. Also, the arrangement density of this spandex yarn is preferably 9 to 18 threads / inch. The raschel fabric can be adjusted by adjusting the thickness, arrangement density, and tension during knitting of the elastic fiber yarn so that the tightening force per 2.54 cm of width (dimension in the direction perpendicular to the pulling direction) at an elongation of 30% in the wale direction is 60 to 85 g, and the tightening force per 2.54 cm of width at an elongation of 30% in the course direction is 30 to 50 g. However, this tightening force is defined as the tension when a 2.54 cm wide sample tape is stretched at a speed of 300 mm / min until the elongation reaches 80%, then contracted at the same speed, and the elongation is recovered to 30%. Furthermore, the non-elastic fiber yarn interwoven with the spandex yarn is not limited to 75 denier, and it is preferably a multifilament yarn of 30 to 100 denier. Note that these yarns may or may not have crimps. Also, the adhesive layer laminated on the back surface of the raschel fabric is preferably an adhesive such as an acrylic-based or rubber-based adhesive, and particularly preferably one having air permeability. The coating thickness (when dry) is preferably 20 to 80 μm.

[0023] The taping material 10 of this embodiment is a net with a chain stitch of non-elastic fiber yarns as columns, and elastic fiber yarns are inserted along this chain stitch. Therefore, it has a large elongation and stretch elasticity in the direction of the chain stitch, that is, the length direction of the taping material 10. And the taping material 10 is a net composed of a first basket weave structure and a second basket weave structure that meander symmetrically left and right. The first basket weave structure and the second basket weave structure intersect at regular intervals, and two adjacent chain stitches are connected at regular pitches with the sinker loops of the above-mentioned non-elastic fiber yarns, and oblong holes are formed between the two chain stitches. And the sinker loops on both sides of one chain stitch are offset from each other by half of the pitch in the front and back and are arranged in a staggered pattern. Therefore, when the stretchable tape is stretched in the width direction, the chain stitches before and after this connection part of the chain stitch by this sinker loop are bent with this connection part as a fulcrum, and each hole between the chain stitches is deformed into a rhombus, and the chain stitches constituting each side of the rhombus stretch obliquely. Therefore, it exhibits a large elongation and stretch elasticity in both the vertical and horizontal directions. In particular, in this embodiment, since the knitted fabric 11 has a hexagonal planar shape, it has a shape similar to the skin structure. Moreover, since it is a knitted fabric having stretchability in both the vertical and horizontal directions, its shock dispersion ability is very excellent. Therefore, by attaching it to a part of the body that hurts when moved or pressed, the skin can regain its flexibility and reduce the pain of muscles and joints. The human skin is an aggregate of polyhedrons composed of 8 hexagonal faces and 6 quadrilateral faces called Kelvin 14-sided bodies, and has a scaly structure in which hexagons are connected when viewed from the surface. Therefore, the skin moves along the hexagonal structure, and it is considered that the impact received on one side of the hexagon is dispersed to each side and washed away. Therefore, by selectively attaching a taping material that closely resembles normal flexible skin to the skin at a painful or hard-shrunk location as in this embodiment, the flexibility of the skin at that part is restored, the pain is dispersed toward any of the six sides, and the pain of muscles and joints can be reduced. By attaching another taping material adjacent to the side where the pain of one taping material is dispersed, the pain is dispersed and reduced in the other taping material. By repeating this adjacent attachment of the taping materials, finally, the symptoms can be significantly improved.

[0024] Furthermore, when the tightening force per 2.54 cm width at 30% elongation in the longitudinal direction is set to 60 - 85 g, and the tightening force per 2.54 cm width at 30% elongation in the transverse direction is set to 30 - 50 g, the most suitable functions under normal use conditions can be obtained, and the application and flexion of joints become easier. However, if the thickness of the spandex yarn is less than 140 denier or the arrangement density is less than 9 threads per inch, the stretch elasticity becomes too small. On the other hand, if the thickness exceeds 420 denier or the arrangement density exceeds 18 threads per inch, the stretch elasticity becomes too large, and it is difficult to obtain the desired functions in either case. Also, if the coating thickness of the adhesive is less than 20 μm, it becomes easy to peel off, and if it exceeds 80 μm, the holes between the above chain stitches are blocked and the air permeability decreases.

[0025] Figure 4 schematically shows the configuration of another embodiment of the taping material of the present invention.

[0026] As shown in Figure 4, the taping material 110 of this embodiment has a honeycomb planar-shaped adhesive layer 112 having at least one hexagonal hole superimposed on the lower surface of a honeycomb planar-shaped knitted fabric 111 (corresponding to the base material of the present invention) having at least one hexagonal hole, and a release paper 113 having at least one hexagonal hole is adhered to the lower surface of this adhesive layer 112. The honeycomb shape is a porous shape like a beehive. In Figure 4, five hexagonal holes are shown, but in the present invention, it may be a planar shape consisting of a single hole of a beehive, or any number of porous shapes.

[0027] The knitted fabric 111 has the same configuration as the knitted fabric 11 in the embodiments of Figures 1 - 3, and the same operational effects of obtaining stretchability in the longitudinal and transverse directions can be obtained. Since the detailed configuration of the knitted fabric 111 is also the same as that of the knitted fabric 11, detailed description is omitted.

[0028] Since the knitted fabric 111 has a hexagonal honeycomb shape, it has a shape similar to the skin structure. Moreover, since it is a knitted fabric having elasticity in both the vertical and horizontal directions, its shock dispersion ability is very excellent. Therefore, by attaching it to a part of the body that hurts when moved or pressed, the skin regains its flexibility and the pain in the muscles and joints can be reduced. The human skin is an aggregate of polyhedrons composed of eight hexagonal faces and six quadrilateral faces called Kelvin tetrakaidecahedra, and has a scaly structure with hexagons connected when viewed from the surface. Therefore, the skin moves along the hexagonal structure, and it is considered that the impact received on one side of the hexagon is dispersed to each side and carried away. Thus, by selectively attaching a taping material that closely resembles normal flexible skin to the skin at a painful or stiffened location as in this embodiment, the flexibility of the skin at that part is restored, the pain is dispersed toward any of the six sides, and the pain in the muscles and joints can be reduced. By attaching another honeycomb-shaped taping material adjacent to the side where the pain of one honeycomb-shaped taping material is dispersed, the pain is dispersed and reduced in the other honeycomb-shaped taping material. By repeating this adjacent attachment of the honeycomb-shaped taping materials, the symptoms can finally be significantly improved.

Example

[0029] Samples of Example 1 were produced in the same manner as the taping material 10 of the embodiment described in relation to FIGS. 1 to 3. In this case, the tension during knitting was set to 20 g. Also, as the elastic fiber yarns 11c and 11d, 210-denier spandex yarns were used, and samples of Example 2 were produced in the same manner as the samples of Example 1, except that the tension during knitting was set to be greater than 20 g and not more than 25 g. Further, samples of Example 3 were produced in the same manner as the samples of Example 1, except that 280-denier spandex yarns were used and the tension during knitting was set to be greater than 25 g and not more than 28 g.

[0030] From the Russell knitted fabrics used in the production of Examples 1 to 3, samples long in the wale direction (warp direction) and samples long in the course direction (weft direction) were each cut into a size of 2.54 cm in width and 10 cm in length. These were attached to an Instron tensile testing machine and pulled in the length direction at a speed of 300 mm / min, and the relationship between the load and elongation until the load reached 2.25 kg was tested. The results are shown in Table 1.

[0031]

Table 1

[0032] Also, the above-mentioned samples were pulled at a speed of 300 mm / min until the elongation reached 80%, and the relationship between the load at that time, that is, the tensile force and the elongation, was tested. The results are shown in Table 2.

Table 2

[0033] Then, after the elongation reached 80%, the above-mentioned elongation was returned at the same speed of 300 mm / min, and the relationship between the load at that time, that is, the tightening force and the elongation, was tested. The results are shown in Table 3.

Table 3

[0034] As is clear from Tables 1 to 3, according to the samples of Examples 1 to 3, it was found that sufficient stretchability can be obtained in both the longitudinal direction (length direction) and the transverse direction (width direction), and the impact dispersion ability is very excellent. As a result, by selectively attaching the taping material of the present invention to the skin at a painful or hard-shrinking part, the flexibility of the skin at that part is restored, and the pain is dispersed, which may reduce the pain of muscles and joints.

[0035] The above-described specific embodiments all illustratively show the present invention and do not show it in a limiting manner. The present invention can be implemented in various other modified forms and changed forms. Therefore, the scope of the present invention is defined only by the scope of claims for utility model registration and its equivalent scope.
